WiFi Networking Problem

Hi, Having problems with my WiFi connection. I added a Wireless - G Range Expander to an existing (working) WiFi connection. Now, even with the Range Expander unplugged, I cannot connect to any websites. I do have a full strength connection. I've tried all of the following: *Rebooted laptop. *Unplugged WiFi modem for 30 seconds and restarted. *Unplugged Range Expander *Repaired connection using Windows "repair" option None of the above worked. I have no problem if I connect directly to my DSL modem via an Ethernet cable. Also, my girlfriend has no problems using her laptop on the same network. Any suggestions would be great. Thanks, Dean
